Major Blud writes: Multiple news outlets are reporting that Theranos, the company that promised to revolutionize healthcare with new blood-testing devices, is closing shop. The company "was unable to sell itself and is now looking to pay unsecured creditors its remaining cash of about $5 million in the upcoming months," reports CBS News. The CEO, Elizabeth Holmes, and President/COO Ramesh Balwani recently settled a civil suit with the SEC, which charged them with massive fraud related to them seeking investment based on misleading information regarding the accuracy of their "Edison" diagnostic equipment. According to The Wall Street Journal, investors lost almost $1 billion in the company. At one point, it was valued at almost $10 billion.

Last August, 50 employees at Three Square Market got RFID chips in their hands. Now 80 have them. From a report: The idea came about in early 2017, president of Three Square Market Patrick McMullan says, when he was on a business trip to Sweden -- a country where some people are getting subcutaneous microchips to do things like enter secure buildings or book train tickets. It's one of very few places where chip implants, which have been around for quite a while, have taken off in some fashion. The chips he and his employees got are about the size of a very large grain of rice. They're intended to make it a little easier to do things like get into the office, log on to computers, and buy food and drinks in the company cafeteria. Like many RFID chips, they are passive -- they don't have batteries, and instead get their power from an RFID reader when it requests data from the chip.

A year into their experiment, McMullan and a few employees say they are still using the chips regularly at work for all the activities they started out with last summer. Since then, an additional 30 employees have gotten the chips, which means that roughly 80 of the company's now 250 employees, or nearly a third, are walking, talking cyborgs. "You get used to it; it's easy," McMullan says. As far as he knows, just two Three Square Market employees have had their chips removed -- and that was when they left the company.

An anonymous reader quotes a report from Live Science: Scientists found that death travels in unremitting waves through a cell, moving at a rate of 30 micrometers (one-thousandth of an inch) every minute, they report in a new study published Aug. 10 in the journal Science. That means, for instance, that a nerve cell, whose body can reach a size of 100 micrometers, could take as long as 3 minutes and 20 seconds to die. Apoptosis -- or programmed cell death -- is necessary for clearing our bodies of unnecessary or harmful cells, such as those that are infected by viruses. It also helps shape organs and other features in a developing fetus.

To figure this out, Ferrell and his team observed the process in one of the larger cells present in nature: egg cells of Xenopus laevis, or African clawed frogs. They filled test tubes with fluid from the eggs and triggered apoptosis, which they watched unfold by tagging involved proteins with fluorescent light. If they saw fluorescent light, it meant apoptosis was taking place. They found that the fluorescent light traveled through the test tubes at a constant speed. If apoptosis had carried on due to simple diffusion (the spreading of substances from an area of high concentration to one of low concentration), the process would have slowed down toward the end, according to the study. Since it didn't, the researchers concluded that the process they observed must be "trigger waves," which they likened to "the spread of a fire through a field." The caspases that are first activated, activate other molecules of caspases, which activate yet others, until the entire cell is destroyed.

We've reached a milestone in gene-edited food, according to the Washington Post. "Calyxt's 'healthier' soybean oil, the industry's first true gene-edited food, could make its way into products such as chips, salad dressings and baked goods as soon as the end of this year." Calyxt's soybean is the first of 23 gene-edited crops the Agriculture Department has recognized to date.... Scientists at Calyxt, a subsidiary of the French pharmaceutical firm Cellectis, developed their soybean by turning "off" the genes responsible for the trans fats in soybean oil. Compared with the conventional version, Calyxt says, oil made from this soybean boasts far more "healthy" fats, and far less of the fats that raise bad cholesterol. Chief executive Federico Tripodi likes to say the product is akin to olive oil but without the pungent flavor that would make it off-putting in Oreos or granola bars.

It has earned praise from the Center for Science in the Public Interest, a consumer group that says public health will benefit from ingredients with less trans and saturated fats, regardless of how they were developed.... Scientists in university labs and at companies such as Calyxt are already designing plants that are more nutritious, convenient and sustainable, they say.... [U]niversities around the country are working on plants that will withstand droughts, diseases and the ravages of climate change. Such improvements, underway in crops as diverse as oranges, wine grapes and cacao, could protect these plants in the future while cutting down water and chemical use, experts say....

While Congress passed a law requiring food makers to disclose genetically modified ingredients in 2016, those rules will probably not apply to foods made with newer gene-editing techniques, said experts who had reviewed it. Calyxt has marketed its soybean oil to food-makers as "non-GMO," citing the fact that it contains no foreign genetic material. But consumers are unlikely to accept this distinction, said Michael Hansen, a senior staff scientist at Consumers Union. Hansen argues that GMOs developed a negative reputation in part because biotech companies botched public outreach in the 1980s and 1990s. Should businesses repeat that mistake, he said, consumers will reject a promising technology.
Non-GM foods are already a multibillion-dollar market, the article points out, adding that according to a 2016 Pew Research Center report, nearly 4 in 10 American consumers believe genetically modified foods are bad for their health.

An anonymous reader shares a report from the BBC involving glyphosate, the world's most common weedkiller: Chemical giant Monsanto has been ordered to pay $289 million in damages to a man who claimed herbicides containing glyphosate had caused his cancer. In a landmark case, a Californian jury found that Monsanto knew its Roundup and RangerPro weedkillers were dangerous and failed to warn consumers. It's the first lawsuit to go to trial alleging a glyphosate link to cancer. Monsanto denies that glyphosate causes cancer and says it intends to appeal against the ruling.

The claimant in the case, groundskeeper Dewayne Johnson, is among more than 5,000 similar plaintiffs across the US. Mr Johnson was diagnosed with non-Hodgkin's lymphoma in 2014. His lawyers said he regularly used a form of RangerPro while working at a school in Benicia, California. Jurors found on Friday that the company had acted with "malice" and that its weedkillers contributed "substantially" to Mr Johnson's terminal illness.

"Australian scientists have taken a 'major step forward' in the world of cancer research," reports ABC (the national broadcaster of Australia). Long-time Slashdot reader Artem Tashkinov quotes an announcement from the Walter and Eliza Hall Institute of Medical Research: In a world first, Melbourne scientists have discovered a new type of anti-cancer drug that can put cancer cells into a permanent sleep, without the harmful side-effects caused by conventional cancer therapies.

Published today in the journal Nature, the research reveals the first class of anti-cancer drugs that work by putting the cancer cell to sleep -- arresting tumour growth and spread without damaging the cells' DNA.

The new class of drugs could provide an exciting alternative for people with cancer, and has already shown great promise in halting cancer progression in models of blood and liver cancers, as well as in delaying cancer relapse.
One of the lead researchers says the new compounds "had already shown great promise in preclinical testing."

The FDA has approved the key ingredient used in the vegetarian-friendly Impossible Burger. "The ingredient, soy leghemoglobin, releases a protein called heme that gives the meat substitute its distinctive blood-like color and taste," reports CNBC. The burger comes from a company aptly named Impossible Foods, which started raising millions of dollars in 2015 to pursue a plant-based burger that truly tastes like meat. From the report: In a letter to Impossible Foods released Monday, the FDA deemed soy leghemoglobin GRAS, or generally recognized as safe, in its most recent review. "Getting a no-questions letter goes above and beyond our strict compliance to all federal food-safety regulations," Impossible Foods founder and CEO Patrick O. Brown said in a statement. "We have prioritized safety and transparency from day one, and they will always be core elements of our company culture."

A team of researchers at Glasgow University have built a robot that uses machine learning to run and analyze its own chemical reaction. The system is able to figure out every reaction that's possible from a given set of starting materials. Ars Technica reports: Most of its parts are dispersed through a fume hood, which ensures safe ventilation of any products that somehow escape the system. The upper right is a collection of tanks containing starting materials and pumps that send them into one of six reaction chambers, which can be operated in parallel. The outcomes of these reactions can then be sent on for analysis. Pumps can feed samples into an IR spectrometer, a mass spectrometer, and a compact NMR machine -- the latter being the only bit of equipment that didn't fit in the fume hood. Collectively, these can create a fingerprint of the molecules that occupy a reaction chamber. By comparing this to the fingerprint of the starting materials, it's possible to determine whether a chemical reaction took place and infer some things about its products.

All of that is a substitute for a chemist's hands, but it doesn't replace the brains that evaluate potential reactions. That's where a machine-learning algorithm comes in. The system was given a set of 72 reactions with known products and used those to generate predictions of the outcomes of further reactions. From there, it started choosing reactions at random from the remaining list of options and determining whether they, too, produced products. By the time the algorithm had sampled 10 percent of the total possible reactions, it was able to predict the outcome of untested reactions with more than 80-percent accuracy. And, since the earlier reactions it tested were chosen at random, the system wasn't biased by human expectations of what reactions would or wouldn't work. The research has been published in the journal Nature.

An anonymous reader quotes Fortune: The causes of Type 1 diabetes can be significantly reversed over several years with just two injections of a common tuberculosis vaccine injected a few weeks apart, researchers at Massachusetts General Hospital announced Thursday in a paper published in the journal Nature. Researchers found a substantial reduction in the blood-sugar marker HbA1c that is used to diagnose diabetes.

All subjects with diabetes who received the vaccine had a 10% reduction after three years and 18% after four years, bringing them below the cutoff point for a clinical diagnosis. Those subjects followed for a full eight years retained most of the reduction. Participants who received a placebo or were in a reference group that followed normal diabetic management saw their blood sugar measurement rise by a few percentage points during the same periods followed... A 10% reduction in Hb1Ac reduces the risk of death as a result of diabetes by 21%, and drops by 37% other complications, like blindness and loss of feeling in hands and feet, according to a 2000 study.

A major U.S. government report warns that advances in synthetic biology now allow scientists to have the capability to recreate dangerous viruses from scratch; make harmful bacteria more deadly; and modify common microbes so that they churn out lethal toxins once they enter the body. The Guardian reports: In the report, the scientists describe how synthetic biology, which gives researchers precision tools to manipulate living organisms, "enhances and expands" opportunities to create bioweapons. "As the power of the technology increases, that brings a general need to scrutinize where harms could come from," said Peter Carr, a senior scientist at MIT's Synthetic Biology Center in Cambridge, Massachusetts.

The report calls on the U.S. government to rethink how it conducts disease surveillance, so it can better detect novel bioweapons, and to look at ways to bolster defenses, for example by finding ways to make and deploy vaccines far more rapidly. For every bioweapon the scientists consider, the report sets out key hurdles that, once cleared, will make the weapons more feasible. The Guardian references a case 20 years ago where geneticist Eckard Wimmer recreated the poliovirus in a test tube. Earlier this year, a team at the University of Alberta built an infectious horse pox virus. "The virus is a close relative of smallpox, which may have claimed half a billion lives in the 20th century," reports The Guardian. "Today, the genetic code of almost any mammalian virus can be found online and synthesized."

The National Institutes of Health is paying a St. Louis university to study the effectiveness of flu vaccines. An anonymous reader quotes Fortune: The university wants volunteers to live in "hotel influenza," where they'd be either given a vaccine or a placebo, be exposed to the flu, and be quarantined for 10 days in the Extended Stay Research Unit. Compensation for such an experiment is around $3,500 (for time and travel), according to a SLU release... "In a traditional flu study, we vaccinate people and see if their immune systems respond by creating antibodies that fight flu," Dr. Hoff said in a release. "In a human challenge study, we vaccinate people, then deliberately challenge their bodies by exposing them to flu to see if they get sick"...

The 24 volunteers living in the "hotel influenza" would have private rooms and bathrooms, common areas with with chairs and TVs, along with exercise equipment, and catered meals in a dining room. They will be observed, "have blood and lung tests and nose swabs to see if they are infected with flu and shedding the virus." If they come down with the flu, they won't be able to leave until they've tested negative for the virus for two days. Nurses would be available around the clock.
One St. Louis newspaper jokes that it will either be a "sickathon" -- or "an indoor vacation complete with catered meals, TV, internet, a gym and views of the Arch".

There's a new surprise from the Wall Street Journal's John Carreyrou (author of the Theranos expose Bad Blood: Secrets and Lies in a Silicon Valley Startup). An anonymous reader shares Vanity Fair's summary of their newest podcast interview: According to Carreyrou, Holmes is currently waltzing around Silicon Valley, meeting with investors, hoping to raise money for an entirely new start-up idea. (My mouth dropped when I heard that, too....) I'm sure she will somehow succeed in convincing someone to hand over millions of dollars, especially if venture capitalists like Tim Draper (an early Theranos investor) are still out there saying the stories by Carreyrou were wrong (they weren't), and that Holmes was on the precipice of saving the world (she wasn't) before the media came after her.

You would think that seeing Holmes's duplicity wrapped up in a neat bow in Carreyrou's book, and in the S.E.C. settlement -- which, incidentally, mentions the term "fraud" seven times -- would force Silicon Valley to perform its own due diligence, and question whether the way C.E.O.s, investors, and the media interact should be re-evaluated. But alas, the tech world doesn't see Theranos as a tech company, but rather a biotech outlier... Of course, there is still a major criminal investigation underway by the F.B.I., one that could end with Holmes behind bars.
Carreyou tells another interviewer that Theranos "is a cautionary tale about the hubris in the Valley... there's certainly a lot of innovation there, but there's also an unbelievable amount of arrogance and pretending."

"Researchers may have identified a compound that can stop some of the most common cold viruses, the rhinovirus, in its tracks, according to a new report published in the journal Nature." An anonymous reader quotes Fortune: The scientists' work is early-stage. But the mechanism it uses to tackle colds is striking. Developed at the Imperial College London, the molecule targets a protein in human cells that cold viruses use in order to replicate and conquer. By targeting this specific pathway, the compound could theoretically be used to thwart most viruses (and since it focuses on human proteins, it may not cause the virus to mutate its way away from danger)...

"The common cold is an inconvenience for most of us, but can cause serious complications in people with conditions like asthma and [chronic lung disease]," said lead researcher Ed Tate in a statement. "A drug like this could be extremely beneficial if given early in infection, and we are working on making a version that could be inhaled, so that it gets to the lungs quickly."

An anonymous reader quotes a report from Ars Technica: Alan Turing is rightly famed for his contributions to computer science. But one of his key concepts -- an autonomous system that can generate complex behavior from a few simple rules -- also has applications in unexpected places, like animal behavior. One area where Turing himself applied the concept is in chemistry, and he published a paper describing how a single chemical reaction could create complex patterns like stripes if certain conditions are met. It took us decades to figure out how to actually implement Turing's ideas about chemistry, but we've managed to create a number of reactions that display the behaviors he described. And now, a team of Chinese researchers has figured out how to use them to make something practical: a highly efficient desalination membrane.

To make this a true Turing-style system, the researchers dissolved a large molecule in water. This had the effect of making the water more viscous, which slowed the diffusion of the activator. In addition, the molecule was chosen so that the activator would stick to it, slowing things down even further. The end result was a system similar to the ones defined over a half-century ago. Imaging of the features show that rather than simply thickening the membrane, the membrane retained the same width in these areas; instead, it bulged out to form the structures. That's critical, as the amount of surface area exposed to a salt solution should influence how much water gets through the membrane. In fact, the researchers confirmed that more water was purified when the new membranes were used (the version with the stripes outperformed the dotted one). Unfortunately, the researchers don't compare this system to commercially available membranes. The report has been published in the journal Science.

An anonymous reader writes: "Amazon, but for Crispr." It's a notion that may sound far-fetched -- but it's exactly what Synthego, a Silicon Valley biotech startup, wants to be. Synthego's first product let scientists order a custom Crispr kit and have it delivered within a week; in the next few weeks, the startup will add custom Crispr'd human cell lines to its on-demand offerings, which will help scientists working on potentially life-saving medicines. Crispr, as this WIRED guide explains, "is a new class of molecular tools that scientists can use to precisely target and cut any kind of genetic material." It's revolutionizing biology -- but neither of Synthego's founders is a biologist. Turns out, in the ever-expanding industry around genome engineering, that's hardly a disqualifier.

Across the country, companies are trying to snag a seat on the fast-moving Crispr train. There's Inscripta, which is gunning to be the Apple of gene-editing by building the biological equivalent of the personal computer. In theory, that hardware will make gene editing as easy as pushing a button. And then there's Twist Biosciences, which can print out a powerful Crispr guide (the tool that identifies the bits of genetic code a scientist is hoping to target) on a single semiconductor chip -- the Intel of genome engineering, if you will. As Megan Molteni writes, "all these analogies to the computing industry are more than just wordplay." Rather, they offer a language for understanding the complex world of Crispr. "Crispr is making biology more programmable than ever before," Molteni writes. "And the biotech execs staking their claims in Crispr's backend systems have read their Silicon Valley history. They're betting biology will be the next great computing platform, DNA will be the code that runs it, and Crispr will be the programming language."

In an April 10 report for biotech clients, Goldman Sachs analysts noted that one-shot cures for diseases are not great for business as they're bad for longterm profits. The investment banks' report, titled "The Genome Revolution," asks clients: "Is curing patients a sustainable business model?" The answer may be "no," according to follow-up information provided. Slashdot reader tomhath shares the report from Ars Technica: Analyst Salveen Richter and colleagues laid it out: "The potential to deliver 'one shot cures' is one of the most attractive aspects of gene therapy, genetically engineered cell therapy, and gene editing. However, such treatments offer a very different outlook with regard to recurring revenue versus chronic therapies... While this proposition carries tremendous value for patients and society, it could represent a challenge for genome medicine developers looking for sustained cash flow."

For a real-world example, they pointed to Gilead Sciences, which markets treatments for hepatitis C that have cure rates exceeding 90 percent. In 2015, the company's hepatitis C treatment sales peaked at $12.5 billion. But as more people were cured and there were fewer infected individuals to spread the disease, sales began to languish. Goldman Sachs analysts estimate that the treatments will bring in less than $4 billion this year. [Gilead]'s rapid rise and fall of its hepatitis C franchise highlights one of the dynamics of an effective drug that permanently cures a disease, resulting in a gradual exhaustion of the prevalent pool of patients," the analysts wrote. The report noted that diseases such as common cancers -- where the "incident pool remains stable" -- are less risky for business.

A few months ago, Theranos laid off almost half of its workforce as it struggled to recover from the backlash generated when the company failed to provide accurate results to patients using its proprietary blood test technology. Now, according to people familiar with the matter, the company is laying off most of its remaining workforce in a last-ditch effort to preserve cash and avert or at least delay bankruptcy for a few more months. MarketWatch reports: Tuesday's layoffs take the company's head count from about 125 employees to two dozen or fewer, according to people familiar with the matter. As recently as late 2015, Theranos had about 800 employees. Elizabeth Holmes, the Silicon Valley firm's founder and chief executive officer, announced the layoffs at an all-employee meeting at Theranos's offices in Newark, Calif. on Tuesday, less than a month after settling civil fraud charges with the U.S. Securities and Exchange Commission. Under the SEC settlement, Holmes was forced to relinquish her voting control over the company she founded 15 years ago as a 19-year-old Stanford dropout, give back a big chunk of her stock, and pay a $500,000 penalty. She also agreed to be barred from being an officer or director in a public company for 10 years.

Researchers at Tufts University are testing tooth-mounted RFID chips which sense and transmit data on what goes in your mouth. ABC News reports: The sensors looks like custom microchips stuck to the tooth. They are flexible, tiny squares -- ranging from 4 mm by 4 mm to an even smaller size of about 2 mm by 2 mm -- that are applied directly to human teeth. Each one has three active layers made of titanium and gold, with a middle layer of either silk fibers or water-based gels. In small-scale studies, four human volunteers wore sensors, which had silk as the middle "detector" layer, on their teeth and swished liquids around in their mouths to see if the sensors would function. The researchers were testing for sugar and for alcohol.

The tiny squares successfully sent wireless signals to tablets and cell phone devices. In one of their first experiments, the chip could tell the difference between solutions of purified water, artificial saliva, 50 percent alcohol and wood alcohol. It would then wirelessly signal to a nearby receiver via radiofrequency, similar to how EZ Passes work. They demonstrated that different concentrations of glucose, a type of sugar, could be distinguished, even in liquids that had sugar concentrations like those found in fruit drinks.

Slashdot reader Bruce66423 shares what researchers learned by studying the effect of drugs on bacteria in the gut: The research reveals that it's not just antibiotics that have the effect of causing resistance to antibiotics. "Of the drugs in the study, 156 were antibacterials (144 antibiotics and 12 antiseptics). But a further 835, such as painkillers and blood-pressure pills, were not intended to harm bacteria. Yet almost a quarter (203) did....

"However, Dr Maier's study also brings some good news for the fight against antimicrobial resistance. Some strains she looked at which were resistant to antibiotics nevertheless succumbed to one or more of the non-antibiotic drugs thrown at them. This could be a starting point for the development of new antimicrobial agents which would eliminate bacteria that have proved intractable to other means."
Every drug the researchers tested has already been approved for human use -- which means they could all eventually be used as a second wave of antibiotics.

An anonymous reader quotes a report from Quartz: The economic engine of Silicon Valley seems to have driven right by the midwest. America's urban coastal cities have enjoyed an explosion in their technology sectors. New York's Silicon Alley and Boston's biotech corridor are world-class incubators of talent and startups. Austin (Texas), Seattle (Washington), Washington, D.C, and even Miami Beach claim a piece of the digital economy (and Silicon-something monikers). But what about Columbus and Indianapolis and Kansas City? After years in the doldrums, their fortunes are rising. Venture capital firms are setting up shop. Startups are clustering in old industrial strongholds. But the region's tech sectors look different than their coastal cousins. The midwest is seeing the rise of "mid-tech."

Alongside the traditional high-flying software jobs that are plentiful in Silicon Valley, mid-tech jobs, loosely defined as tech jobs requiring less than a college degree, are growing fast in the Midwest. While not an official designation, mid-tech jobs can be defined as skilled tech work that doesn't require a college degree: just intense, focused training on the job or in vocational programs like those of blue-collar trades of the industrial past. [...] Mid-tech jobs composed more than a quarter of all tech employment in major midwestern metropolitan areas, including Columbus, Ohio; Cincinnati, Ohio; St. Louis, Missouri; Detroit, Michigan; Nashville, Tennessee; and Minneapolis-St. Paul, Minnesota-Wisconsin. More than 100,000 people were employed in such jobs in these cities alone. That proportion never cracked 20% in Bay Area metropolises, the heart of Silicon Valley. While the analyses did not include all cities, it reveals the tech sector's evolution in the Midwest along different lines than Silicon Valley. The findings come from the Brookings Institute, a nonprofit public policy research group, which crunched data from the Bureau of Labor Statistics. High and mid-tech jobs in midwestern cities also grew at an annual compounded rate of about 5%. What do these jobs look like? "In Kentucky, the technical skills once applied to things like calculating blast trajectories in mines are going into Javascript," reports Quartz. "The software firm Interapt has set up a training program in Eastern Kentucky to turn former coal miners and others with technical aptitude into software developers."
